Possibility to set API_KEY in runtime

[dresl]

Hi, it would be nice to set API key of email backend manually during runtime (from Admin), not just in settings. I have a project that needs to set multiple EmailBackends with multiple api keys. Would it be possible to add a setter like set_api_key to EmailBackend?

Resolved by adding api_key to kwargs as backend constructor.

You can use django.core.mail.get_connection() to create an email backend instance with custom settings:

from django.conf import settings
from django.core.mail import get_connection, EmailMessage

connection1 = get_connection(settings.EMAIL_BACKEND, api_key="api-key-1")
send_mail("Sent using api-key-1", ..., connection=connection1)

connection2 = get_connection(settings.EMAIL_BACKEND, api_key="api-key-2")
send_mail("Sent using api-key-2", ..., connection=connection2)

message = EmailMessage("Also sent using api-key-2", ..., connection=connection2)
message.send()

You can override almost all Anymail backend settings this way. So you could use get_connection(..., api_url="https://europe-api-endpoint...") to override the default API URL and send certain messages via your ESP's European servers.

In Anymail's docs, see Anymail settings reference for more info on settings overrides, and Mixing email backends for some specific get_connection() examples.
